In the parameter dialog I can set the minimum and maximum value of the parameter.
But how can I limit the value when I generate the c-code?

When generating C code from a Simulink model, you can limit the value of a parameter by adding constraints to the generated code.
  • Create an if statement in your C code generated:
Example:
This code checks if myParam is less than minVal and sets it to minVal if true. Similarly,
it checks if myParam is greater than maxVal and sets it to maxVal if true.
if (myParam < minVal) {
myParam = minVal;
}
if (myParam > maxVal) {
myParam = maxVal;
}
  • Integrate the If Statement into Generated Code
  • Ensure correct placement of the if statement in the generated code.
  • Regenerate code
By following these steps, you can enforce limits on a parameter's value when generating C code from your Simulink model. This ensures that the parameter stays within the specified range during code execution.
